Detailed Description
A Phase III randomized, modified double-blind, multi-centric, comparative study, to evaluate the noninferiority of immunogenicity and safety of single strain oral cholera vaccine Hillchol® (BBV131) to the comparator vaccine Shanchol™ along with lot-to-lot consistency of Hillchol® (BBV131) Study Population: A total of 1800 participants will be enrolled in three descending age groups (Group I- >18, Group II: > 5 to <18 and Group-III: >1 to <5) in 3(1350):1(450) ratio. In each group 600 participants will be enrolled and among 600 participants 450 participants will receive any lot of Hillchol® (BBV131) and 150 participants will receive Shanchol™. Study objectives: Primary Objectives: 1) To demonstrate non-inferiority of immunogenicity Hillchol®(BBV131) to that of Shanchol by comparing the seroconversion rate (defined as '4 fold rise in vibriocidal antibody titer compared to baseline') upon administration of 2 doses of Hillchol®(BBV131) or Shanchol, across all age groups. Secondary Secondary objectives: To evaluate and compare the immunogenicity of Hillchol®(BBV131) with that of Shanchol across all age groups, by comparing the geometric mean titers (GMT) of vibriocidal antibodies in participants receiving Hillchol®(BBV131) and ShancholTM. To evaluate and compare the frequency and severity of all solicited and unsolicited adverse events upon administration of two doses of Hillchol®(BBV131) or ShancholTM, among all three age groups. Exploratory Objectives: 1)To demonstrate the consistency of immunogenicity for 3 consecutive lots of Hillchol®(BBV131) (lot-to-lot consistency) across all age groups, by comparing the GMT of vibriocidal antibodies in participants receiving doses from each vaccine lot of Hillchol®(BBV131). Study Endpoints/Outcome: The proportion of participants achieving seroconversion against Ogawa serotype, 14 days after 2 doses of test or comparator vaccine. The proportion of participants achieving seroconversion against Inaba serotype, 14 days after 2 doses of test or comparator vaccine. Geometric Mean Titers (GMT) of anti-Ogawa antibodies two weeks after 2 doses of Test or comparator vaccine GMT of anti-Inaba antibodies two weeks after 2 doses of Test or comparator vaccine. Immediate reaction: Within 30 mins of administration of each dose. Incidence, intensity, the causality of all solicited adverse events during the 7-day follow-up period after each dose. Incidence, intensity, the causality of unsolicited adverse events during the 14-day follow-up period after each dose. Incidence, intensity, the causality of all adverse events and Serious Adverse Events (SAEs) during the entire study period. The proportion of participants achieving seroconversion against Ogawa and Inaba serotype, 14 days after 2 doses for each consecutive batch of Hillchol®(BBV131). Sero-conversion is defined as a 4-fold rise above the baseline 14 days post-second dose Geometric mean of vibriocidal antibody titers to be calculated. Study design: In this study, a total sample size of 1800 participants will be enrolled in three groups in age descending manner and administered with Hillchol®(BBV131) or Shanchol™. A) Group-I (Age :> 18): In this group, a total of 600 participants aged >18 will be enrolled and randomly assigned into 1:1:1:1 ratio to receive either any three lots of Hillchol®(BBV131) (150: Lot-I, 150: Lot-II and 150: Lot-III) or Shanchol® (150) on day 0 and 14. After completion of 7 days post, 1st dose for 40 participants (Hillchol (BBV131):10-Lot-I, 10-Lot-II,10-Lot-III and 10-shanchol) in the Group I, safety data of these participants will be reviewed by Data Safety Monitoring Board (DSMB) and based on their recommendation, the study will progress by recruiting remaining 560 participants in the group I and starting recruitment of participants for group II. B) Group-II (Age: >5 to <18): In this group, a total of 600 participants aged >5 to <18 will be enrolled and randomly assigned into 1:1:1:1 ratio to receive either any three lots of Hillchol® (BBV131)(150: Lot-I, 150: Lot-II and 150: Lot-III) or Shanchol®(150)on day 0 and 14. After completion of 7 days post 1st dose for 40 participants (Hillchol (BBV131):10-Lot-I,10-Lot-II,10-Lot-III and 10-shanchol) in the Group II, safety data of these participants will be reviewed by the Data Safety Monitoring Board (DSMB) and based on their recommendation, the study will progress by recruiting remaining 560 participants in the group II and starting recruitment of participants for group III. C) Group-III (Age: >1 to <5): In this group, a total of 600 participants aged >1 to <5 will be enrolled and randomly assigned into 1:1:1:1 ratio to receive either any three lots of Hillchol® (BBV131) (150: Lot-I, 150: Lot-II and 150: Lot-III) or Shanchol® (150) on day 0 and 14. After completion of 7 days post, 1st dose for 40 participants (Hillchol (BBV131): 10-Lot-I, 10-Lot-II, 10-Lot-III and 10-shanchol) in the Group III, the safety data of these subjects will be reviewed by the Data Safety Monitoring Board (DSMB) and based on their recommendation, the study will progress by recruiting the remaining 560 participants in the group III.
